DNDC 模型在稻田生态系统中的研究进展及应用
Advance and application of DNDC model in paddy ecosystem
摘要
Abstract
DNDC model (DeNitrification-DeComposition model) is a process-oriented model that predicts carbon and nitrogen dynamics via coupling of biogeochemistry processes to ecologic environmental factors,which also has a well prediction of greenhouse gas emissions from rice paddy. Advance and application of DNDC model in paddy ecosystem were reviewed, including crop growth, greenhouse gases emissions and nitrogen loss from paddy field. The results showed that modeled results of crop growth, methane emissions, and nitrogen loss fitted observed values well after years of improvement. However, DNDC model still has its disadvantages in rice varieties,management techniques, and nitrous oxide reproducibility. These findings have implication for model improvement on the variety of rice type, input data of agricultural management, and the mechanism of nitrous oxide emissions to provide theoretical support in greenhouse gases emissions mitigation and establish a reliable evaluation method on paddy ecosystem.关键词
